First of all, don't we have a "What do YOU want from a Superman game" Thread? Did we need one dedicated to you?
Second, it's great you have your own little wishlist there, but have you tried to think about what it is you're asking for? Making games at the size we have now takes years and costs tens of MILLIONS of dollars. You're basically asking for a game that allows you to explore 2 giant cities, an ancient island with Greece architecture, and an all new planet which is populated by millions of different aliens. Asking for that is unreasonable, and frankly impossible unless the developers decide to half-ass it.
Third, I understand that the idea of a weakened Superman may not appeal to people. But the fact of the matter is, he is too damn powerful to be playable and balanced in an action game. As far as I see it, we can either complain that Superman is taking hits he obviously shouldn't, can't kill enemies he normally would one-hit destroy, and being able to die in combat, or they could get some talented writers to come up with a story that explains how and why Superman would actually work in a video game.
